Your computer screen is also referred to in IT as a monitor or PC monitor. The technology behind the monitor has changed drastically over the years. In addition to showing images, the monitor has become increasingly popular as an input device, such as the iPad or tablet with a touch-sensitive touch screen.
The monitor was already in use in the 1970s and at that time could only display the color green, also known as monochrome monitors. These screens were still very thick at the time. This was due to the built-in CRT, also known as CRT. Screens were not only thick at the time, they were also heavy due to the use of glass. The color display came in the 1980s. Still heavy and heavier because these color screens, also known as televisions, were getting bigger.
The CRT screen (so the fat television) could be tiring for the eyes because the image is built up line by line. So it seems to flicker slightly. This was less due to an ever higher refresh rate, also known as 60hz, 80hz and 100hz televisions.
Anyway, these thick screens are now a thing of the past. The screen you are using now probably has an LCD panel. An LCD screen works with "liquid crystals" that can give a certain color by electric current. This does not require a thick picture tube and screens can be flat and light. On the contrary to CRT screens, LCD screens do not suffer from flicker. However, there is another important feature to consider when purchasing an LCD screen. This is also known as the response time. That is the time it takes to change the colors. The higher this response time (indicated in MS), the higher the chance that a delay will be noticeable.
Within the LCD screens there are different types of screens. A distinction is made here by the active matrix technology. This technology influences the color reproduction and response time. These types of screens are referred to as TFT, IPS, TFD and SLCD. The beautiful screens in, for example, the iPad, iPhone, iMac or MacBook are also due to the good color reproduction of IPS.
Another type of flat monitor is the OLED screen. Unlike LCD, OLED uses a different way of giving light. The advantage of OLED is better black display, better viewing angles, lighter, thinner and more economical. Often there is some discussion of which two screens have the better color reproduction; IPS LCD or OLED.
Most contemporary screens used in the office workplace are flat and use LCD technology. Well-known brands are HP, Dell, and Iliyama. The screens have also got bigger over time. In the 1990s, the 17-inch was used and nowadays it is the 21 ", 22" or 23 "inch screen. The resolution has also increased. Because more can be shown at the same time, one can also be more productive.
Precisely because the monitor has become larger and larger, it is important that you also sit properly and that the eyes are not overtired by looking at a screen. A solution for this is to raise the monitor with a monitor stand. In the 1970s this problem was soon encountered and you will find these monitor standards for old CRT monitors. Not much has changed to date, which is a shame. The monitor standards of that time were purely functional, while with the popularity of Apple products, the computers may also be "beautiful".
